## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight collision with terrain/water, takeoff
  - weather condition - high density altitude (contributing factor)
  - preflight planning/preparation - inadequate, pilot in command (cause)

## Analysis

THE PLT HAD REDUCED THE SPRAY LOAD FROM 90 TO 50 GALS TO COMPENSATE FOR THE INCREASE IN DENSITY ALTITUDE. THE WINDS WERE BLOWING LIGHTLY DURING PREVIOUS TAKEOFFS BUT WERE CALM DURING THIS TAKEOFF. AS THE HELICOPTER HOVERED FORWARD DURING THE TAKEOFF IT FAILED TO OBTAIN TRANSLATIONAL LIFT & IMPACTED THE GROUND.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19820720032879A](https://openairdocs.org/incident/19820720032879A), Jul 20, 1982: Bell OH13ETEXHELI, Milan, MO, Substantial damage. Helicopter failed to attain translational lift after lift off. Settled to ground. Impact cut off tail boom.

## Other investigations on N38117 (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
